True story: Khun Krisada & Khun Nawaporn Loedwong — 1-bedroom condo, Asok

Khun Krisada works from home with the AC running 12 hours daily. His 6-year-old condo never had a deep coil clean. Khun Nawaporn developed chronic cough. Opening the balcony door, the outside air actually feels fresher than inside. AC coil inspection revealed black mold and MVOC (microbial volatile organic compounds) floating through the room.

The Problem

• AC coil mold: Penicillium, Cladosporium
• MVOCs cause chronic headaches
• Stale water smell from drainage
• Monthly antihistamine bills
• Standard AC cleaning only surface

Why Normal Fixes Fail

Standard AC cleaning only wipes panels and outer coil. Mold spores remain in aluminum fins and drainage. Alcohol disinfectant evaporates without breaking MVOCs. HEPA purifiers filter spores but don't destroy MVOCs.

Solution: WHD Ozone Reset

WHD places a 10,000 mg/h ozone unit in the living room and runs the AC during treatment for 4-6 hours. Ozone is pulled into the AC system, destroying coil mold, drainage mold, and airborne MVOCs in one step. Khun Nawaporn's cough cleared in 3 days.

10 Reasons WHD Solves AC + MVOC Problems

1. 10,000 mg/h ozone pulled into AC during treatment
2. Destroys coil mold Penicillium, Cladosporium 99.99%
3. Breaks down MVOCs causing chronic headaches
4. Kills drainage mold wipes can't reach
5. Eliminates musty odor — not masking
6. Zero residue — decays to O₂

9. Guaranteed — redo free
10. Khun Nawaporn's cough cleared in 3 days
